Carrying Capacity Test

Carrying capacity is a unit of measurement that is used in all sorts of manners. In the study of biology, it looks at the number of people, animals, and crops that a region can support without harming the environment, but it is also a term used to see how many people can fit inside areas like a vehicle or an elevator where volume and weight are a concern. What else do you know about it?
